How about?

 gen NewVar=.
 forv y=2000/2010 {
 	replace NewVar=Value`y' if FirstYear==`y'
 }


hth,

Hi everyone,

I am not sure whether the following is possible in Stata and, if yes,
how to address the problem.

I want to assign a new variable a value that is already stored in a
second variable. The problem is that I need a value of a variable that
is calculated dynamically. Let me explain it in a short example: Assume
I have the following variables:

FirstYear
Value2000
Value2001
Value2002
...
Value2010


What I need is something like
. gen NewVariable = Value[String(FirstYear + 1)]
that would read the value out of Value2006 if FirstYear had the value
2005. Is this possible in Stata? Would I need to write a macro for that?



Thanks and best regards
Markus
